Path Correction Error

[Till812]

Hi,

First of all, thank you for providing this Python package – it has been a huge help! The example programs in particular make it really easy to get started and build custom solutions.

I'm currently trying to use the PathCorrection functionality with the EGM module. Unfortunately, even after setting everything up in Virtual Environmentin RobotStudio and on the Python side, I consistently run into the following error:

50452 – External Interface Cyclic Error

I wanted to ask if there are any specific example programs available that demonstrate how to implement PathCorrection, or if anyone has successfully used it with the EGM module via the UdpUc device to perform real-time path adjustments.

Any advice or pointers would be greatly appreciated!

Best regards, Till

Thanks a lot for your feedback! I know real use cases where PathCorrection has been successfully implemented. I’ll try to gather some example programs and put together a basic example to illustrate how to use this feature. 🏭

I just created an example for you, and it’s working as expected. I initially forgot to create an External Motion Interface Data with 'path' level in the Motion configuration, so I spent some time figuring that out.

As a bonus, here’s the video result :

@Till812 The error might be related to the path correction mode (\APTR or \LATR). You should use \APTR if the LTAPP protocol is not used.

Hello Flo-ABB
thank you very much for the detailed answer, it helped me a lot especially the last hint with \ATPR \LATR was something I haven't seen anywhere before.
